Mode emerges from stealth with new approach to software-defined WANs

Mode, a San Francisco-based startup, came out of stealth today with a new approach to software-defined wide area networks they call software-defined core network (SD-CORE), which they say will dramatically reduce the cost of running these networks over traditional methods. The company also announced a total of $24 million in funding led by GV and […] Continue reading Mode emerges from stealth with new approach to software-defined WANs

Building Transistors with Transistors

Since the 1940s when the first transistor was created, transistors have evolved from ornery blocks of germanium wrangled into basic amplifiers into thousands and thousands of different devices made of all kinds of material that make any number of electrical applications possible, cheap, and reliable. MOSFETs can come in at least four types: P- or N-channel, and enhancement or depletion mode. They also bear different power ratings. And some varieties are more loved than others; for instance, depletion-mode, N-channel power MOSFETs are comparatively scarce. [DeepSOIC] was trying to find one before he decided to make his own by hacking a …read more
